Hi, this is my first post and I admit it was because I've been having problems. Sorry in advance for the length.
It started when my Logitech wireless mouse and keyboard combo became slow and intermittent. That was soon followed by internet connection problems through Firefox which also affected my Mozilla email account. 'Connection is not secure'. Basically my usual sites (and servers) were supposedly set up insecurely and required temporary exemption certificates. The internet became unusable, as you can imagine.
I used the laptop to test the internet and there were no problems which told me the fault was inside my desktop, and it wasn't connected with my router.The Logitech .DLL issue Missing Entry: Logifetch etc, was simply done by relocating the wireless receiver in another USB port. The certificate problem remained.
I tried numerous routes to resolve the problem including using Malware-bytes on top of my McAfee suite to see if anything nasty had got through.
In Task Manager I found something odd under 'apps running' so opened the file in its location which was in a folder (C:/Prog Files/b0cdf084161ec60384cda43e155c3e4d). Inside was an executable programme with a symbol of a dog inside a red circle with a red slash across it. There was an icon below which looks like a magnifying glass (but could be a key), followed by 5 Application extension files and 2 DAT files.
There was on first inspection two seemingly identical executable files (3718f65992eb0faa57b160e73ff72435.exe) so in my desperate state I tried to delete the whole folder by shredding it in McAfee. The only thing that disappeared was the second executable file. The good thing was that the problem of the security certificate and exemption certificates had gone, and all seems to be normal with one difference.
The search tool in the Firefox browser switched from DuckDuck Go to Google. Could the problem have been with my search tool?
Anyway I don't know how this problem happened but others use my desktop. The weird folder is still intact and defies any deletion or alteration, so I have a few questions to put to this forum.
1 Do I need anything else to sit along McAfee to boost security?
2 Is the executable file known, and is it dangerous?
3 Could there be any link between my mouse/keyboard problems and my internet security issue?
Thanks for your time in advance.
